CALEA Integration and Lawful Intercept Compliance
Lawful Intercept (LI) allows the Law Enforcement Agencies (LEA) to perform an authorized electronic surveillance.
Depending on the country of operation, the service providers (SPs) are required to support LI in their respective
networks.
In the United States, SPs are required to ensure LI compliance based on Communications Assistance for Law
Enforcement Act (CALEA) specifications.
Instant supports CALEA integration in a hierarchical and flat topology, mesh OAW-IAP network, wired and wireless
networks.
Enable this feature only if lawful interception is authorized by a Law enforcement agency.
CALEA Server Integration
To support CALEA integration and ensure LI compliance, you can configure the OAW-IAPs to replicate a specific or
selected client traffic and send it to a remote CALEA server.
Traffic Flow from IAP to CALEA Server
You can configure an OAW-IAP to send GRE encapsulated packets to the CALEA server and replicate client traffic
within the GRE tunnel. Each OAW-IAP sends GRE encapsulated packets only for its associated or connected
clients. The following figure illustrates the traffic flow from the OAW-IAP to the CALEA server.
